PUMPING APPARATUS.

Specification of Letters Patent.

Patented Dec. 9, 191 3.

Application filed May 2, 1913. Serial No. 765,045.

Be it knownthat I, LELAND WJIpLi's, a citizen of the United States,residing at Grenloch, New Jersey, have invented certain Improvements, inPumping Apparatus,

of which the following is a specification.

My invention relates to that class of pumps which are normally suppliedfrom atank, the object of my invention belng to provide for the fillingof the tank by the pump while still maintaining the supply to said pumpwhen a source of supply lnde- {pendent of the tank is available. Thisobject I attain in themanner hereinafter set forth, reference being hadto the accompanying drawing, in which 7 Figure 1 is a diagrammatic viewof a pump and tank equipped in accordance with my invention; Fig. 2 is alongitudinal section, on a larger scale, of that portion of theapparatus to which my invention particularly relates, and F ig. 3 is atransverse section on the line aa, Fig. 2.

In Fig. 1 of the drawing, 1 represents the barrel of the pump which isnormally suplied from a tank 2, the latter communicating with theinduction chest 3 of the pump through a pipe 4.

The eduot-ion chest 5 of the pump has an air chamber (j and a dischargepipe 7 and the supply pipe 4 has a branch pipe 8 whereby the supply forthe pump can be drawn from a Well, a stream, or other source of supply,when such source is available. In order that this independent source ofsupply may also, at the same time, be used for filling or refilling thetank 2, I provide the delivery pipe 7 of the pump with a branch pipe 9terminating in an injector nozzle 10 which projects into a chamber 11contained within a casing 12, the latter ex- 4 tendingtransversely'across an enlarged portion 13 of the branch pipe 8 andhaving, at

the bottom, a flanged inlet opening 14 communicating with said pipe 8,the enlargement 13 being of such dimensions that a.

is being supplied from the tank 2 the valves in the pipes 8, 9 and 16will be closed and those in the pipes 4 and 7 opened. When, however, theindependent source of supply is available, the valves in the pipes 8, 9and 16 will be opened, the valve in the pipe 4 closed and that in thepipe 7 closed or partially closed, so as to cause the discharge, or aportion of the discharge, from the pump to be directed through the pipe9 to the injector 10. A portion of the supply flowing through the pipe 8will therefore be caused to enter the chamber 11 and will, by the actionof the injector 10, be forced through thepipe 16 into the tank 2. Whenthe latter has been filled or refilled the valves in the pipes 8, 9 and16 may be closed and the valves in the pipes 4 and 7 opened so as tosupply the pump from the tank, or, if the independent supply is stillavailable, the valve in the pipe 8 may remain open and that in the pipe4 may remain closed until it again becomes necessary for the pump todraw its supply from the tank 2.

Instead of using the injector construction shown, the pipe 9 may deliverdirectly into the tank if desired.

I claim:

1. The combination of a pump and a supply tank therefor, with a pipe forsupplying the pump from a source independent of the tank, and meanswhereby the pump may be caused to force into the tank liquid derivedfrom said independent supply pipe.

2. The combination of a pump and a supply tank therefor, witha pipe forsupplying the pump from a source independent of the tank, said pipebeing also in connnunication with the tank and being provided with aninjector in communication with the discharge from the pump, whereby aportion of the liquid flowing through said pipe may be diverted andforced into the tank.

3-. The combination of a pump and a supply tank therefor, with a pipefor supplying the pump from a source independent of the tank, aninject-ion chamber casing communicating with said pipe and with thetank, and an injector communicating with the discharge of the pumpandserving to cause flow of liquid into and through the injection chamberand thence to the tank.

4. The combination of a pump and a supply tank therefor, with a pipe forsupplying the pump from a source independent of the tank, an injectionchamber casing crossing said pipe and having an inlet communicating withthe interior, of the pipe and an outlet communicating with the tank, and'an injector in communication with the dischargeof the pump and servingto cause passage of the fluid from said supply pipe I into and throughsaid casing and thence to the tank.

5. The combination of a pump and a supply tank therefor, with a pipe forsupplying the pump from a source independent of the tank, an injectionchamber casing crossing a portion of said pipe Which is enlarged in sizeso as to provide a passage around said casing, an inlet in said casingcommunieating with the interior of the enlarged portion of the pipe, adelivery branch on said casing communicating with the tank, and aninjector communicating with the discharge of the pump and serving tocause flow of liquid from the pipe into and through the injectionchamber casing and thence to the tank. 5

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
